GALVAN IC BATTERY.

SPECIFICATION forming part of Letters lPatent No. 443,976, dated December 30, 1890.

Application filed July 14, 1890. Serial No. 358,618. (No model.)

To @ZZ whom t may concern:

Be it known that I, GEORGE A. SMITH, of Halifax, in the Province of Nova Scotia and Dominion of Canada, have invented a new and Improved Galvanic Battery, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which-- Figure l is a vertical transverse section of my improved battery. Fig. 2 is a side elevation of my improved battery, showing the battery-case in section. Fig. 3 is an exterior view or the battery-case, and Fig. 4 is aperspective view of the elements.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to construct a simple, inexpensive, and powerful battery for the use of physicians, surgeons, and experimentalists for generating` a strong current for operating` induction-coils, galvanocautery, running motors, and for other purposes.

My invention consists in a battery formed of a cell for containing the exciting-liquid, one or more elements formed of rods of zinc and rods of carbon, and mechanism for plunging and lifting the elements and holding them at any desired height, all as will be hereinafter more fully described.

The cell A, which contains the exciting-liquid B, is inelosed in a case C, in which are arranged the rods d a', forming guides for the board ZJ, which supports the zinc rods c and the carbon rods d, The carbon and zine rods are mounted in rows in bars c of conducting material, the several rows being separated from each other by plates f, of insulating material. The bars e and the platesf are heldin position by bolts g passing through the said bars and plates and through L-shaped plates 7L 7L', clamping the several parts together. The bolts g are insulated from the zinc plate by rubber tubes surrounding the bolts. To the bar e, attached to the zine rods C, is secured a binding-post t', andto the L- shaped plate ZL is secured a binding-post y. The lower ends of the rods a a are secured to the bottom of the case O, while the upper ends of the said rods are received in brackets Zt 7c', projecting inwardly from the sides of the case.

In the case C is journaled a rock-shaft E, to which are attached one or more arms Z, said arm being connected with an ear m, secured to the under surface of the board b. I'Vhen there are two battery elements, one arm Zwill suffice for raising` and lowering said elements; but when there are a large number of elements two or more of the arms Z will be required. One of the arms Z is prolonged beyond the rock-shaft E and is connected with one end of the spiral spring n, the other end of which extends through a bracket o, at tached to the side of the case C. The said spring n nearly or quite counterbalances the weight of the battery elements.

Upon the end of the rock-shaft E which projects through the end of the casing C is mounted a lever F, which extends underneath the curved ratchet-bar G, attached to the end of the casing, and serves to raise or lower the elements by turning the rock-shaft E, Zhen the lever F is to be operated by hand, it is arranged as shown in full lines in Fig. 3; but when itis operated by foot it is extended downwardly and its lower end is curved outwardly, as shown in dotted lines in the same figure.

The battery is connected with the induction-coil or other apparatus by wires inserted in the bindingposts tj, and the elements are plunged more or less in the excitinguid B by the movement of the lever F. Then the battery is not in use, the elements are removed from the solution by moving the lever F in the opposite direction.

The construction of my improved battery affords a large surface to the action of the liquid, and the rods being separated permit of the free circulation of the solution.

A portion of the front of the battery-casing' is made removable to admit of taking out the battery-cell.

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patentl. A battery element comprising alternating rows of carbon and zine rods, bars of conducting material connecting the rods of each IOC row, insulating-plates between the upper ends of said bars, and the transverse bolts passing through said plates and bars and insulated f rom the bar connecting the zinc rods, substantially as set fort-l1. V

2. A battery element comprising the alternating rows of carbon and zinc rods, bars of conducting material connecting the rods of each row, insulating-plates between said bars, the L-shaped plates at opposite sides of the element, and the transverse bolts passing through the Vertical members of the said plates and through the said bars and insulating-plates, the bolts being insulated from the bars connecting the zinc rods, substantially as set forth.

3. The combination, with the cell having vertical rods or guides, of an element in the Y-vertical rods or guides, of an element in the cell provided with a board movable vertically on said rods or guides, and a counterbalanced pivoted arm Within the cell connected to the said board and provided exterior to the cell with an operating-lever, Substantially as set forth.

GEORGE A. SMITH.
